Description
Technical field
The utility model relates to a kind of wind-driven generator, particularly a kind of high efficiency compound oar blade type Double-rotor wind-driven generator.
Background technique
Along with global energy shortage, wind-power electricity generation more and more obtains the attention of Ge great electricity power enterprise, and country is also using wind-power electricity generation as strategic industry.In existing wind-driven generator, mostly adopt blade to drive the mode of generator rotation to generate electricity, want to improve the power of generator, generally adopt in two ways, increase the length of blade or the rotating speed of increase blade, still, due to the restriction of material, above-mentioned two kinds of approach have reached the limit of Modern Manufacturing Technology, be difficult to continue again expansion potential, therefore need to find in addition the power that new thinking improves wind-driven generator.
Model utility content
Goal of the invention of the present utility model is a kind of compound oar blade type Double-rotor wind-driven generator that can effectively improve generator power and efficiency of design, and its concrete technological scheme is:
A kind of compound oar blade type Double-rotor wind-driven generator, comprise generator body, generator body is fixed on generator pylon by pedestal, generator body interior comprises internal rotor and external rotor, external rotor connects inner side blade by the outer shaft of hollow, and internal rotor connects outside blade by axis, and external axle sleeve is in the outside of axis, between outer shaft and axis, be provided with oiling agent and bearing, the direction of rotation of inner side blade and outside blade.
Adopt technique scheme, can effectively improve efficiency and the specific power of wind-driven generator.
Accompanying drawing explanation
The schematic diagram of the compound oar blade type Double-rotor wind-driven generator of Fig. 1.
Wherein, 1-internal rotor; 2-external rotor; 3-outer shaft; 4-axis; Blade inside 5-; Blade outside 6-; 7-generator body; 8-pedestal.
Embodiment
The embodiment who sets forth below represents and allows those skilled in the art to put into practice necessary information of the present utility model, and illustrates and put into practice best mode of the present utility model.Once read with reference to the accompanying drawings following description, those skilled in the art just will understand design of the present utility model and will recognize the application of these designs of not illustrating especially herein.Should be appreciated that these designs and application fall into the scope of disclosure and the accompanying claims book.
With reference to a kind of compound oar blade type Double-rotor wind-driven generator shown in accompanying drawing 1, comprise generator body 7, generator body 7 is fixed on generator pylon by pedestal 8, generator body 7 inside comprise internal rotor 1 and external rotor 2, external rotor 2 connects inner side blade 5 by the outer shaft 3 of hollow, and internal rotor 1 connects outside blade 6 by axis 3, and outer shaft 3 is enclosed within the outside of axis 4, between outer shaft 3 and axis 4, be provided with oiling agent and bearing, the direction of rotation of inner side blade 5 and outside blade 6.
Owing to having adopted dual-rotor structure, can the in the situation that of equal wind speed, realize the power of conventional wind power generator twice, wind-driven generator does not need too large blade, has reduced difficulty and the cost manufactured.The eddy current that the inside and outside blade of combined type can effectively utilize outside blade 6 to rotate drives inner side blade 5, has improved the utilization ratio of wind.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all mode of executions.And these belong to apparent variation that spirit of the present utility model extended out or change still among protection domain of the present utility model.
